The Center for Biological Diversity and the Environmental Protection Information Center sued the U.S. Fish and Wildlife Servicefor failing to act on a 2012 petition to protect Shasta salamanders under the Endangered Species Act.

Since the petition was filed, the species was split into three distinct species, each of which is rare and imperiled.

The salamanders are imminently threatened by plans to raise the height of Northern California’s Shasta Dam, which would result in extensive flooding of their habitat.

The Center sued the Trump administration for refusing to recognize that ocean acidification caused by fossil fuel pollution is impairing the quality of Oregon’s coastal waters. The lawsuit notes that the Environmental Protection Agency is violating the Clean Water Act by failing to identify waters impaired by ocean acidification. That would allow those waters to be subject to pollution controls and other protective measures.

The Center sued the Trump administration to expose a secretive program that denies Endangered Species Act protection to imperiled species like the Pacific walrus. The lawsui follows controversy over the Species Status Assessment (SSA) program. Using the SSA, Interior Sec. Ryan Zinke and the Trump administration have denied protection to the walrus and are preparing to strip safeguards from the Canada lynx and American burying beetle.

Conservation groups including the Center sued the U.S. Fish and Wildlife Service to protect critical habitat for endangered Florida bonneted bats. On the brink of extinction, the bat has been devastated by habitat loss to urban and agricultural sprawl and now faces the new threat of climate change driven sea-level rise.

The Humane Society of the United States, Humane Society International, Center for Biological Diversity and Born Free USA sued the U.S. Fish and Wildlife Service today for violating the law by failing to post online elephant and lion trophy-permitting records on the Internet.

The Center sued the U.S. Fish and Wildlife Service today for failing to protect lifesaving critical habitat for the western yellow-billed cuckoo in Arizona, New Mexico, California, Colorado and other western states.

The Center, as part of a broad coalition of conservation and citizens’ groups, sued the Trump administration late Friday to challenge the Bureau of Land Management rescinding most provisions of its 2016 methane waste rule.

The lawsuit, filed in U.S. District Court in San Francisco, notes that Interior Secretary Ryan Zinke’s BLM illegally rescinded the rule, which requires oil and gas companies operating on public lands to take reasonable measures to prevent the waste of publicly owned natural gas. Such measures significantly reduce pollution from methane, a dangerously potent greenhouse gas.

The Center and ally conservation groups sued the Trump administration for leasing more than 115,000 acres of public land in western Colorado and northern Utah for oil and gas development without adequate environmental protections. These lease sales, offered by the Bureau of Land Management, violate federal environmental laws and will worsen air quality in a region already laden with harmful levels of ozone pollution.

The Center sued the Trump administration for refusing to release public records related to the government’s failure to develop greenhouse gas emission standards for airplanes as required by the Clean Air Act.
